Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

The server power supply is a conversion device for supplying power to the server device, and converts ac/dc power into a voltage that can support the operation of the device, typically 12V and 54V. Conventionally, as the power of the server is lower, the 1+1 redundancy design is generally realized by using 2 power modules, so that the normal operation of the server can be ensured, but as the data volume is increased and the processing speed is increased, the demand on calculation power is higher and higher, and the energy consumption is required to be increased accordingly, such as a GPU server, a whole cabinet server and the like, a plurality of power supply units Power Supply Unit, PSU for short, are required to be combined to meet the power demand of the equipment, so that the application scene of a multi-power system appears, the power variation range is large for the system, the existing scheme is effective for the system with less power supply quantity, such as a 1+1 or 2+1 redundancy system, the power supply quantity is less, the system control is simple, and the implementation is easy. If the number of power supplies is large, the management unit alone can not adjust the power supplies to deal with the large load change. For a multi-power system, when the system power is low, part of power sources can be actively turned off for energy saving, but if the number of the turned-off power sources is large, for example, when the working power sources cannot bear the full power of the system design, the adjustment is poor in timeliness through the adjustment of the management unit, and at the moment, the risk of downtime of the system exists.

Based on this, according to an embodiment of the present invention, there is provided a power control method embodiment, it being noted that the steps shown in the flowcharts of the drawings may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that herein.

In this embodiment, a power control method is provided, where the method is applied to a power control system, where the power control system includes a control terminal and a power cluster, where the control terminal is connected to each power source in the power cluster, and the method is performed by the control terminal, for example, a separate management board card or a server BMC, and fig. 1 is a flowchart of the power control method according to an embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:

in step S101, the load of each power supply in the plurality of power supplies of the power supply cluster is monitored.

Specifically, for example, when the power supply cluster system is powered on, the management unit of the control terminal detects the load condition of the power supply.

In an alternative example, the power source may be a PSU.

Step S102, determining a load range of the power load of the first power supply.

Specifically, the first power supply is any one of the plurality of power supplies.

In an alternative example, the load range may be a range representing a high load section, a range of a normal load section, and a range of a low load section, which are set by humans. For example, when the power supply cluster system is powered on, the control end can detect the load condition of each power supply, and in the case of multiple power supplies, because of the use of a load balancing mechanism, the load of each power supply is generally almost the same. For example, a load section to which the current load of the first power supply belongs may be determined by taking a section greater than 70% of the maximum load as a high load range, a section of 30% to 70% as a normal load range, and a section less than 30% as a low load range.

Step S103, when the current load range of the power load of the first power supply is the first preset load range, determining a control strategy corresponding to the first preset load range.

Specifically, a mapping relationship between the first preset load range and the control policy may be set, and according to the load range to which the first power supply currently belongs, a corresponding control policy is determined, for example, turning on the power supply, turning off the power supply, dormancy power supply, or reducing the power of the power supply, etc.

Step S104, selecting a target power supply from a plurality of groups of power supplies to execute the control strategy based on the control strategy.

Specifically, the control policy may select one or more power supplies to execute, for example, when the power supply needs to be turned on, one power supply or multiple power supplies may be selectively turned on according to the power supply requirement, and a selection condition may be set, for example, a power supply is selected from a group with the least number of turned on power supplies, or a power supply with the longest sleep time is selected to be turned on.

The power control method provided by the embodiment monitors the power load of each power supply in a plurality of groups of power supplies of the power supply cluster; determining a current load range of a power supply load of a first power supply, wherein the first power supply is any power supply in a plurality of groups of power supplies; when the current load range of the power load of the first power supply is a first preset load range, determining a control strategy corresponding to the first preset load range; and selecting a target power supply from the plurality of groups of power supplies to execute the control strategy based on the control strategy. The power supply control method has the advantages that the load range of the power supply load can be determined by monitoring the power supply load of the power supply, then the control strategy corresponding to the load range is determined, and the target power supply is selected from a plurality of groups of power supplies to execute the control strategy based on the control strategy, so that the power supply can be controlled more finely, the power supply condition can be timely reflected by monitoring the power supply load, the real-time performance of management is improved, meanwhile, the control strategy is timely adjusted through the load change, the energy conservation is facilitated, and the excessive waste of energy is avoided.

step a1, selecting one power supply with the longest sleep time from each group of power supplies of the plurality of groups of power supplies as a target starting power supply.

Specifically, in an alternative example, the first load range may be a load range greater than 70%, representing a high load range; the second load range may be a 70% to 30% load range, including 70% and 30% is representative of a normal load range; the third load range may be a load range of less than 30%, representing a low load range. When the current load range of the power supply load of the first power supply is the first load range, that is, more than 70%, the power supply load is generally higher at this time, and the system has a certain risk, and the power supply in dormancy needs to be started to balance the load, so that one power supply with the longest dormancy time is selected from each group of power supplies of the multiple groups of power supplies as a target starting power supply. The power supplies may be grouped in ways, for example, in 2 power supplies, with one power supply having the longest sleep time being selected from each of the power supplies.

And a2, sequencing all the target starting power supplies according to the sleep time to obtain a first sequencing queue.

Specifically, the target starting power supply is sequenced according to the sleep time, and a first sequencing queue is obtained.

And a step a3, generating a first power supply control strategy according to the first sequencing queue.

Specifically, the first power control strategy includes: and starting the target starting power supply in sequence according to the first sequencing queue until the load range of the load of the first power supply is the second load range. The power supply with the longest sleep time is started preferentially, the load of each power supply is monitored in real time in the starting process, and when the load reaches the normal load range, the rest target starting power supplies are stopped.

Step b1, extracting the sleep time of each power supply in the plurality of groups of power supplies.

And b2, sequencing all the power supplies according to the sleep time to obtain a second sequencing queue.

And b3, generating a second power supply control strategy according to the second sequencing queue.

Specifically, the second power control strategy includes: and sequentially starting the power supplies in the second sequencing queue according to the second sequencing queue. The sleep time of each power supply in the plurality of groups of power supplies is extracted, all the power supplies are sequenced according to the sleep time, a second sequencing queue is obtained, the power supplies in the second sequencing queue are sequentially started according to the second sequencing queue, meanwhile, the power supply load of each power supply can be monitored in real time during starting, and the starting of the rest sleep power supplies is stopped when the load reaches a normal range.

In an alternative example, the preferred load may be set to a target load, for example 60% of the maximum load, and the starting of the remaining power supply is stopped when the load of the first power supply reaches 60% at the time of starting.

step c1, respectively extracting a power supply from each group of power supplies of a plurality of groups of power supplies as a target dormancy power supply;

step c2, sequencing the target dormancy power supply to generate a third sequencing queue;

and c3, generating a third power supply control strategy according to the third sequencing queue.

Specifically, the third power control strategy includes: and executing dormancy operation on the target dormancy power supply according to the third ordering queue.

In particular, the third load range may be, for example, a load range of less than 30% of the maximum load. When the current load range of the power load of the first power supply is the third load range, the power load is lower at this moment, the efficiency of the power supply is not ideal, the control end can enable some power supplies to sleep so as to improve the power supply efficiency, and considering that a general machine room is multi-path power supply, for example, two paths of power supply are adopted, the power supply module redundancy mode is generally N+N and N+M redundancy, if N+N redundancy is adopted, namely 2N power supplies (for example PSU) are respectively connected to AB two paths of the machine room for power supply, if one path of PSU is always in sleep, the other path of PSU is in sleep, and normal operation of the system cannot be ensured; therefore, it is preferable to follow the AB two paths to be turned on alternately or simultaneously, so that even when one path is powered off, the situation that the powered device is directly powered off will not occur.

It should be noted that, the sleep power supply in the present application means that the power supply reduces the output voltage, exits from the system to flow uniformly, but is still in an on-line state.

By the above mode, the third load range is a range with lower load, which represents lower efficiency of the power supply, and in order to save energy, a part of the power supplies can be alternately turned off from a plurality of groups of power supplies, namely, one power supply is respectively extracted from each group of power supplies as a target dormancy power supply, the target dormancy power supplies are sequenced, and dormancy operation is sequentially performed on the target dormancy power supplies, so that the utilization rate of the power supplies can be improved.

In an alternative embodiment, the method further comprises the method steps as shown in fig. 2:

in step S201, the number of power sources in the on state in each group of power sources is obtained, and the total number of the on power sources is determined.

In step S202, when it is determined that the total number of turned-on power supplies is smaller than the target number of power supplies, an authorized operation is performed on one or more of the power supplies in the sleep state.

In step S203, when the sum of the authorized power supply number and the total power supply number meets the preset requirement, the operation of authorizing the dormant power supply is stopped.

Specifically, in the design of a power supply system, there is a redundant design generally, when a power supply is dormant, it is required to ensure that other power supplies except the redundant power supply can perform self-control starting operation, so that when a power supply control end fails or fails to perform control, for example, under the condition of large-range jump of a load, the control end is easy to monitor and not timely cause the condition that a control instruction is not timely sent, and the dormant power supply is authorized, so that the power supply end can determine which power supplies have the capability of controlling the self-starting.

The sum of the number of the started power supplies and the number of the authorized power supplies in the dormancy is the number of other power supplies except the redundant power supplies in the power supply cluster, so that when the power supply equipment (such as a machine room server device) operates at the maximum power, even if the power supply control end cannot control the power supply to supply power, the power supply can complete power supply according to the authorized power supplies, and the stable operation of the system can be ensured.

Specifically, when one power supply circuit in the powered device is powered off, a two-way power supply is generally designed under normal conditions, if one power supply circuit is powered off, the situation of insufficient instantaneous power supply of the powered device can occur, and all power supplies in a dormant state are started at the moment, so that electric energy can be timely supplied to the powered device.

Specifically, a register flag bit can be set in the micro control unit MCU of the power supply as an authorization flag bit, and the flag bit is set to a preset authorization value, for example, 1 during authorization, so that authorization can be conveniently performed, and meanwhile, the authorization state of the power supply can be rapidly and accurately judged.

In an alternative embodiment, the method further comprises:

the sleep time of each target power-on is cleared.

Specifically, the target starting power supply is started and simultaneously clears the sleep time of the target starting power supply, and accumulation of the sleep time is not caused, so that the current sleep time is obtained when the power supply needs to be started each time, and the target starting power supply has a reference value more than the accumulated sleep time.

In an alternative embodiment, the method further comprises:

the target power supply number is used for indicating the number of power supplies capable of meeting the maximum power of the equipment to be powered.

Specifically, the number of power supplies meeting the maximum power of the equipment to be powered can ensure that the power supply is sufficient when the equipment to be powered works at the maximum power, and two modes are provided, namely a power supply control end and a power supply end.

In this embodiment, a power control method is provided, where the method is applied to a power control system, where the power control system includes a control terminal and a power cluster, where the control terminal is connected to each power supply in the power cluster, and the method is performed by any one of the power supplies, for example, a micro control unit MCU in the power supply, and fig. 3 is a flowchart of the power control method according to an embodiment of the present invention, and as shown in fig. 3, the flowchart includes the following steps:

step S301, monitoring the operation state of the device.

Specifically, for example, the MCU chip of the power supply can be used for monitoring the running state of the MCU chip in real time.

In step S302, when the operation state is determined to be the on state, the self load is monitored.

Specifically, the MCU may also monitor its own load, and it should be noted that, in this application, the sleep power supply means that the power supply reduces the output voltage, exits from the system to flow equalization, but is still in an on-line state. Because the dormant power supply does not participate in system current sharing, the self-load is not required to be monitored, and only when the power supply is in an on state, the self-load is monitored so as to adopt a corresponding power supply control strategy by using the self-load later.

Step S303, determining a load range to which the own load currently belongs.

Specifically, a plurality of load ranges may be preset, and the load of the load device and the plurality of load ranges are compared to determine the current load range of the load device.

Step S304, when the load range to which the self load currently belongs is determined to be a second preset load range, determining a state control strategy corresponding to the second preset load range.

Specifically, a mapping relationship between a plurality of load ranges and a state control policy is preset, and a corresponding state control policy is determined according to a load range to which a self load currently belongs, for example, a power supply is turned on, a power supply is turned off, or self output power is increased or decreased, which may be specifically defined according to actual situations.

Step S305 controls the power supply state of itself based on the state control policy.

Specifically, based on a state control policy, the power state of the self is controlled, for example, the self is turned on, the self is controlled to enter a sleep state, or the output power of the self is changed.

The power supply control method provided by the embodiment monitors the running state of the power supply control method; when the running state is determined to be an opening state, monitoring the load of the self-body; determining the current load range of the self load; when the current load range of the self load is determined to be a second preset load range, determining a state control strategy corresponding to the second preset load range; and controlling the power supply state of the power supply based on the state control strategy. The control terminal can fail or the load changes drastically, when the control terminal is out of control, the power supply controls the state of the control terminal, the abrupt change of the load can be timely dealt with, and the stable operation of the system is better ensured.

and shielding the dormancy instruction sent by the control terminal.

Specifically, the fourth load range may be a load interval greater than or equal to 70% and less than 90% of the maximum load of the power supply control terminal, if the main load is detected to be greater than or equal to 70%, the rapid increase process of the load is considered, the management unit detects whether the data is likely to be a low load or not, the judgment is performed before the load is increased, the power supply control terminal will send a power supply closing instruction at this time, the PSU has detected the load to be greater than 70%, if one PSU is closed, the system will have a downtime risk, and therefore the power supply selects a dormancy instruction sent by the shielding control terminal under the load, and the dormancy operation is not performed.

and reducing the self output voltage to the target early warning voltage.

Specifically, the fifth load range may be a load interval greater than or equal to 90% of the maximum load, when the load is detected to be greater than 90% and the load pressure is too high, the power supply may trigger the pre-overpower alarm function to reduce the voltage to a target early-warning voltage, so that other power supplies adjust the running state according to the target early-warning voltage.

In an alternative example, the value of the change register OCW1 may be set to a preset early warning value, such as "1" or "0", for example, when the self-load is detected to be greater than or equal to 90% of the maximum load, and the self-output voltage may be reduced to a target early warning voltage, such as 95% of the normal output voltage, when the power supply detects that the value of the self-register is the preset early warning value.

In an alternative embodiment, the method further comprises:

when the operational state is determined to be the sleep state, the bus voltage is monitored.

Specifically, the sleep state of the power supply in the application refers to that the output voltage is reduced, the system current sharing is exited and the power supply is in an on-line state, so that the MCU of the power supply in sleep is still in a working state, and the bus voltage can be monitored in real time.

And when the bus voltage is determined to be smaller than or equal to a preset voltage threshold value, acquiring the authority state of the bus voltage.

Specifically, the preset voltage threshold is a set threshold, and is set according to different power types, for example, 97% of rated voltage of the power supply.

Specifically, when the power supply in dormancy detects that the bus voltage is smaller than or equal to a preset voltage threshold, the value of an authorization register in a register is searched, the authorization state is determined according to the value, when the authorization state is determined, the operation is started, and in this case, when the voltage is smaller than or equal to the preset voltage threshold, the condition that the system load exceeds the rated power consumption of the power supply at the moment is indicated, the power supply is insufficient, all authorized power supplies are started, the maximum power consumption of the system can be ensured, and the electric energy is timely supplied.

Specifically, the powered device may be a server of a machine room, and generally is powered by two or more paths, and the MCU of the power supply may also monitor the status of each path of power supply circuit in the powered device, whether normal or failure occurs.

When any one of the power supply circuits of the power supply equipment is monitored to be in a power-off state, all power supplies in the power supply circuit cannot supply power at the moment, and other power supplies in dormancy need to be started in time so as to ensure the power supply of the server system.

In an alternative example, the state of the power supply circuit may be detected by the power control terminal, for example, the management unit of the power control terminal, and the power supply signal, for example, the psuunifield signal, may be detected, and when a signal abnormality is detected, an instruction may be issued to turn on all the power supplies that are already in sleep.

In an alternative example, the state of the power supply circuit can also be detected through the power supply end, for example, by detecting the load condition of the power supply, when the load of the power supply is increased extremely rapidly and is increased to a higher load (for example, more than 90 percent) in an extremely short time, the problem of power supply circuit failure can occur, at this time, all dormant power supplies are quickly turned on, and an alarm message can be sent to prompt the staff to overhaul and maintain in time.

In order to make the implementation of the method of the present application clearer, the present application further provides a specific application scenario embodiment, for example, in the multi-power supply system shown in fig. 4, a two-way design is generally adopted, the power supplies are PSUs, the power supply control end may be an independent management board card or BMC, where a management unit may be set to control the power supplies, the management unit is in communication connection with the power supplies, and monitors the load condition of each power supply in real time, in the multi-power supply system, a load balancing mechanism is generally adopted, and meanwhile, an energy saving mechanism is also adopted, and in the running process, a part of the power supplies may be turned off according to the load condition, so that the energy saving purpose is achieved, because the load balancing mechanism, the loads of the multiple started power supplies are almost equal, and therefore, the power supply load of any power supply in the multi-power supply system can be detected as a control condition.

The control flow of the management unit is shown in fig. 5, and the management unit detects the PSU load x whenWhen the power load does not reach the normal load interval, the management unit selects one power supply with the longest sleep time from the other path to be started, or when detecting +. >The management unit alternately sleeps one PSU in each power supply and starts the sleep timer of the sleeping PSU.

The control flow of the power supply end is shown in FIG. 6, and the PSU detects the bus voltageWhen->Controlling the authorized power supply to be fully turned on, wherein +.>Delay 1 for target warning voltage00ms, the power supply resumes the output voltage U, and at the same time, the PSU detects the self-output load y, when determining the self-load +.>Mask the sleep instruction sent by the management unit if +.>Triggering a warning function, e.g. changing the value of register OCW1, the PSU output voltage is reduced to +.>，Can be 95% of the normal output voltage, OCW1 is an interrupt handling register for adjusting and controlling the interrupt handling in operation when +.>The value of the register can be set to 1 when it is detected that the value of the register is set to 1, the PSU output voltage is reduced to +.>。

The mode solves the problem that the system load is possibly unable to be handled by the control terminal when the system is in large jump through designing the management unit and PSU software, and the management unit is responsible for starting or dormancy management of the power supply, especially under an N+N system, through time management, the AB two-way alternate switching is realized, and the problem that the power supply of a machine room is abnormal in a dormant state due to a certain excessive power supply is avoided, so that the system is down is solved. After one path of the machine room is powered off, the management unit can start the dormant power supply, and normal operation of the system is ensured. When PSU realizes large jump of load, especially when load increases, the function of starting the dormancy power supply is realized through regulating voltage, and system downtime caused by communication lag of the management unit is avoided.
